【iCore1S 双核心板_ARM】例程十一：RTC实时时钟实验——显示时间和日期

实验现象：

 

核心代码：

int main(void)

  /* USER CODE BEGIN 1 */
        RTC_DateTypeDef sDate;
        RTC_TimeTypeDef sTime;
        uint8_t second_tmp = 0;
  /* USER CODE END 1 */

  /* MCU Configuration----------------------------------------------------------*/

  /* Reset of all peripherals, Initializes the Flash interface and the Systick. */
  HAL_Init();

  /* Configure the system clock */
  SystemClock_Config();

  /* Initialize all configured peripherals */
  MX_GPIO_Init();
  MX_RTC_Init();
  MX_USART1_UART_Init();
  SystemClock_Config();

  /* USER CODE BEGIN 2 */
    LED_RED_ON;                                                                                             //ºìµÆ³£ÁÁ

    usart1.printf("\r\n\r\nhello! I am iCore1S!\r\n\r\n\r\n");

  /* USER CODE END 2 */

  /* Infinite loop */
  /* USER CODE BEGIN WHILE */
  while (1)

      HAL_Delay(100);                                                                                 //¶ÁÈ¡RTCÈÕÆÚºÍʱ¼ä
